Recently, Rabin criticized the use of diminishing marginal utility in explaining risk aversion in small gambles with a mathematical theorem, which compares revealed risk averting behavior in small gambles to the risk behavior implied by expected utility theory in somewhat larger gambles, using...

We proffer a method to assess the adequacy of expected utility theory (EUT) in empirical studies involving discrete and continuous choices. The method calibrates a utility function to revealed choices and rejects EUT for absurd degrees of implied concavity over the wealth at risk. We find EUT...

The choice of deflators of commodity prices can change the time-series properties of the original series. This is a specific application of the general phenomenon that various kinds of data transformations can create spurious cycles that did not exist in the original data. Different empirical...

A dynamic econometric model of the U.S. kiwifruit industry provides a framework for empirical analysis of small-scale commodities, particularly those used by producers for diversification. Production and marketing processes are explained by annual and monthly components, respectively. Results...

A rational expectations storage model is used to simulate monthly corn prices, which are used to evaluate marketing strategies to manage price risk. The data are generated and analyzed in two formats: for long-run outcomes over 10,000 "years" of monthly prices and for 10,000 cases of 40-year...

To assess the impact of BSE in Japan, a Japanese meat demand system is estimated as a gradual switching Rotterdam model. The results, based on data from April 1994 to May 2002, suggest the structural transition took five months from its discovery. The scare affected both domestic and imported beef.

This study examines whether the EU, the world's largest importer, exercises market power over soybean imports. Results, based on 1975-2000 data, suggest that the EU has practiced price discrimination against imports from Argentina and Brazil. The evidence for the practice of pricing-to-market...

This presentation will report results of research that shows that a portfolio of wheat varieties can enhance profitability and reduce risk over the selection of a single variety. Many Kansas wheat farmers select varieties based on average yield. This study uses portfolio theory from business...
